Corvids protect themselves by tricking their enemies (deception). Section 3: Summary Completion When recovering their caches later, the jays preferentially

Beyond tool manufacture, corvids possess what psychologists call "episodic memory"—the ability to recall specific past events, including what happened, where, and when. In a landmark study at the University of Cambridge, scrub jays ( Aphelocoma californica ) cached food in two distinct locations. They learned that one type of food perished quickly while the other remained edible. When recovering their caches later, the jays preferentially searched for the durable food first, ignoring the perishable item. This indicates they mentally traveled back in time to encode the what-where-when of their caching. When recovering their caches later

Corvids also exhibit episodic-like memory —the ability to recall the ‘what, where, and when’ of past events. Scrub jays, for example, hide food caches. If they notice another bird watching them hide food, they will return later to move the cache to a new location. This indicates not only memory but also theory of mind : understanding that another individual has knowledge (and might steal the food). Similarly, ravens have been shown to remember the calls of specific humans who threatened them, holding grudges for years.
